Quanah already responded. But I have to ask - why in the world do you
even need to ask a question like this? Just look in the man page first,
then it will be obvious that it is (or isn't) documented.

Is it really faster and more efficient for you to email hundreds or
thousands of people with a question, than to look at the man pages
already distributed with the software?

You are right.

But on the other hand: Why does not someone get the most recent
information on the project web site itself?

When he checked the web man page on openldap.org
http://www.openldap.org/software/man.cgi , he got old information.
You cannot blame someone for checking "your" official source of
information, can you?

At least you should add an disclaimer on the side to tell people:
"Recent information is only available with the source tarball."
